2.8.7. Change PHP version for console

Attention!

Changing the PHP version for console does not affect the PHP version of the site. For the site, use the instruction Change PHP version for site.

Current version

Command to see the current version of PHP: 

php -v

Change version

Control panel

Affects all new connections via SSH.
  1. Open the "Linux configuration" section.
  2. In the "PHP version" block, select the desired version and click "Save":
  3. Run the command source ~/.bashrc or . ~/.bashrc or simply reconnect via SSH.

Interpreter

Affects only commands that are run with a specific interpreter specified.

When running commands, explicitly specify the path to the PHP interpreter of the desired version: 

/usr/local/php52/bin/php
/usr/local/php53/bin/php
/usr/local/php54/bin/php
/usr/local/php55/bin/php
/usr/local/php56/bin/php
/usr/local/php70/bin/php
/usr/local/php71/bin/php
/usr/local/php72/bin/php
/usr/local/php73/bin/php
/usr/local/php74/bin/php
/usr/local/php80/bin/php
/usr/local/php81/bin/php
/usr/local/php82/bin/php
/usr/local/php83/bin/php
/usr/local/php84/bin/php
/usr/local/php85/bin/php

Either use shortened links like /usr/bin/php8.5 or just php8.5 (instead of 8.5 specify the desired version).

Alias

Attention!

To work with Composer, use version changing via the control panel or PATH. Aliases are also not suitable for use in PHP scripts, Bash scripts, cron and Supervisor — in these cases, you must specify the absolute path to the interpreter of the required PHP version.
  1. Open the "Linux configuration" section.
  2. In the "Aliases" block, enter php in the first field and the command /usr/local/php85/bin/php in the second field (instead of php85, specify the desired version) and click "Save":
  3. Run the command source ~/.bashrc or . ~/.bashrc or simply reconnect via SSH.

PATH

Only affects the current SSH connection. To make the version apply to new connections, use the version changing via the control panel.

Redefine the PATH variable with the command (instead of php85, specify the desired version): 

export PATH=/usr/local/php85/bin:$PATH
